Warning

The wrong settings of the multiplier and external clock in certain circumstances may cause CPU
damage. Setting the working frequency higher than the PCI chipset or processor specs, may cause
abnormal memory module functioning, system hangs, hard disk drive data lose, abnormal functioning
of the VGA card, or abnormal functioning with other add-on cards. Using non-specification settings
for your CPU is not the intention of this explanation. These should be used for engineering testing, not
for normal applications.
If you use non-specification settings for normal operation, your system may not be stable, and may
effect system reliability. Also, we do not guarantee the stability and compatibility for settings that are
not within specification, and any damage of any elements on the motherboard or peripherals, is not
our responsibility.
External Clock:
After choosing the “CPU Operating Speed” option as “Use Define”, you can choose the figure of
external clock from 50~250MHz.
Note: CPU bus speed above 66MHz/100MHz/133MHz is supported but not guaranteed due to the PCI
and chipset limitation.
FSB Rate (CPU:SDRAM:PCI):
You can choose the ratio among 2:3:1
)
3:3:1
)
4:3:1
)
4:4:1
Multiplier Factor:
You can choose from the following multiplier factors: 2.0

12.0 (The
Coppermine CPU does not support the multiplier factors of 2.0 and 2.5)
Note: According to Celeron
™
PPGA MMX processor types, some Celeron
™
PPGA MMX processors
will have the multiplier factor locked and the signal disabled. In this situation, there is no way to
choose a higher multiplier factor.
System Memory Frequency:
You can select the operating frequency for the main system memory. There are three options available:
100MHz, 133MHz, and Auto. The default setting is 100MHz.
Speed Error Hold:
The default setting is “Disabled”. If you change the setting to “Enabled” when the CPU speed setting is
wrong, the system will hold.
